: Store the 25 KG units in a cool, dry, and secure location away from incompatible substances (such as strong oxidizing or reducing agents). Keep containers tightly closed when not in use.
Highly stable under variable thermal ranges, ensuring the chemical does not degrade inside high-temperature heat exchangers.
: Serves under precise dosing controls to prevent surface scaling, keeping heat-transfer surfaces clean and reducing energy consumption. Technical Profile and Characteristics
To evaluate if NALCO 8457 is perfectly suited for your infrastructure, consult a designated Nalco Water Field Engineer to run a comprehensive water chemistry profile on your facility's system. nalco 8457
Do not treat Nalco 8457 as a line item. Treat it as an insurance policy for your heat transfer efficiency. Pair it with regular Nalco TRASAR monitoring and quarterly controller calibrations for maximum asset life.
Dosage is strictly controlled by measuring the pH of the condensate return.
If your facility is struggling with condensate corrosion or high iron returns, it may be time to evaluate whether a filming amine program like Nalco 8457 is the solution you need. : Store the 25 KG units in a
| Parameter | Target Range | |-----------|---------------| | pH | 7.0 – 8.5 | | Orthophosphate (as PO₄³⁻) | 5 – 15 ppm | | Conductivity | < 3000 µS/cm (site specific) | | Calcium hardness (as CaCO₃) | 200 – 800 ppm |
